Abstract
A resilient sealing element is adapted for connection to a well tool, with an integral anchoring device, such as a slip, embedded therein. When compressive forces are applied thereto the sealing element compresses and moves its outside diameter and the slip into sealable engagement with the inside wall of a well tubing or casing. Releasing the sealing and anchoring element is accomplished by applying tension to a wire which passes longitudinally therethrough to cause retraction of the slip.
